The email entered does not match an email associated with a GAME ID (This would include if you have in the past, registered in with a Federated ID) For Example, if you registered with a Facebook ID, that email is not stored on GAME systems. So if you try to enter the email on your Facebook account to try and sent a reset password, it will not work. Instead, simply just click the Facebook icon on the sign in screen to go straight into your GAME Account.
